... Ordering number : EN8765 LA6541ND Overview The LA6541ND is a four-channel driver IC for CD players and recorders (four BTL amplifier channels). Features • Four BTL connection power amplifier channels • max 0.7A • Built-in level shifters • Muting circuit (on/off control of all outputs) (This circuit applies to the BTL amplifier circuits. It does not control operation of the regulator.) • ...

... BTL amplifiers will be on, and the when MUTE is low, all the BTL amplifiers will be off. *4: The 5V regulator voltage when the RESET pin goes from high to low. *5: The 5V regulator voltage difference between the RESET pin going from high to low the RESET pin going from low to high. That is, the hysteresis. LA6541ND Symbol Conditions ...
